Phoronix: Mesa 21.2's Direct3D 12 Driver Now Allows For Easy Multi-GPU Selection

Mesa's Direct3D 12 driver maintained by Microsoft as part of their WSL and Windows OpenGL-over-D3D12 efforts has added a means of being able to select between multiple GPUs/adapters...

Great to see that Microsoft is extending so much in the kernel and userspace for linux.

This type of "extending" is known as Metastasis.

Anybody has an idea why they are doing that in the first place? A developer run-off (doesn't feel like it)? Or did they just accept the fact, that they lost the war on dominating with windows besides being a gamer platform and are just adapting out of necessity?
I think it's a nice feature. Makes windows a little less painful to use if you are forced by an employer .... but is there any real reason to assume this is EEE besides fear?

ARM GPU drivers can be broke AF. If they can implement D3D12, then microsoft has a bigass OpenGL stack they can run on top of it

Has Mesa control panel ever been realized?

Because it lets them make a paravirtual GPU interface for only windows hosts. and doing this. Basically you can expose all DX12 devices to linux and allow WSL, or maybe even hyper-v in the future. (Ive heard rumors, nothing more) and allow an app to directly use any GPU you want.

You should be glad that Microsoft is embracing and extending the linux stack so much. They love Linux you know. Especially the GPL.

It enables companies that use mainly Linux servers (or companies that develop Linux applications) to keep their developers desktops to still be Windows machines, they know that they have lost the server space to Linux and don't want to risk having the desktop follow so to speak, so by making Windows be a "good place to develop for Linux" the IT departments everywhere can still demand to have a 100% Windows fleet.
